To have sons, taran's must have incestious sex.
Then, to have a daughter, a normal woman must eat that 3 leaf mugwort when she has her very first period ever. She must take it every month until she stops bleeding completely.
When that happen, the taran male has sex with the normal woman. The taran must sleep with that woman for a year. After that, she takes the remedy given by Philippe and gets her period again. The normal woman gets pregnant.
When the son and daughter are born from the sister and human, the half-siblings sleep together to make a son, and then that very son will in his turn search for a normal woman to create a sister-wife to his son.
And this went on for a 1000 years i think
